EN 13624 Chemical Disinfectants and Antiseptics: Quantitative Suspension Test for the Evaluation of Fungicidal or Yeasticidal Activity for Instruments Used in the Medical Area

Summary of Test

The EN method below is designed to evaluate the bactericidal, fungicidal, yeasticidal, basic sporicidal or mycobactericidal activity of a product used under various conditions. Many methods are suspension based and are used to support general antimicrobial claims while other test methods are carrier-based and are used to support antimicrobial activity of products on surfaces or devices. In either case, the same general principles apply. The test organism is exposed to sample of the product in a manner which simulates the desired claim. Following exposure, the test system is neutralized and quantitatively assayed for survivors. The resulting plates are incubated, enumerated, and a reduction in viability or microbiocidal effect is determined as compared to a population control.

Test Organisms

Candida albicans, Aspergillus brasiliensis

Purpose of Test

Suspension-based study formally used to evaluate fungicidal or yeasticidal activity of products that are used in the medical area for disinfecting instruments by immersion.

Typical Performance Criteria

(Requirements may vary by claim)

4log reduction in ≤60 minutes
